I've gotten in several discussions recently about the dangers of vaccinations, particularly with regard to the fear that vaccinated children have an increased risk of becoming autistic. I'm not sure who came up with this idea to begin with, but it has since been fully debunked.

Despite the scientific evidence, however, many still cling to this unfounded fear. (We have Jenny McCarthy and Oprah to thank for this.) An increasing number of parents are deciding to play it "safe" by not giving their children the triple vaccine designed to protect against measles, mumps, and rubella. As a result, measles is making a comeback.
